Gage.



avlium; s. :n.501 miam, 'Fammi-nvm To all whom it may concern:

Be it known that I, ALKER S. Mm, Jr,

a citizen of the United States, residingat Madera, in the county ofClearfield and- State of Pennsylvania, have invented new and usefulImprovements in Gages, of which the following is a specification.

This ,invention relates to gages and in particular to a double-endedmarkinggage for use. by-earpenters or the like.

The primary object of the invention is to provide a gage of thislcharacter which includes a single bar of cylindrical construction uponwhich the slides are mounted, ahd which has marking elements provided atthe ends thereof.

A further object is to provide radially adjustable marking elements at'the ends of 'the bar which also are adapted to engage.

the slides to limit the outward movement thereof, the said slides beingprovided with longitudinal slots in communication with their cylindricalbores for the reception of the respective marking elements, when theformer' are turned into4 the proper angular relation thereto? to permitwithdrawal of the slides.

,\ still further object the provision-of -iueans for securing each slidenormally against rotation upon the' bar during its lvngitudinaladjustment thereon, the @aid means serving to secure the slide in adiius-'ted position and being adaptednormally to maintain the same in suchangular rela tion to the bar that its slots will be out of alincmentwith the corresponding marking element.

The invention consists in the features of construction. combination. andarrangementof parts. hereinafter fully described and claimed. referencebeing had to the accor. panyng drawing. in which:

Figure i a side elevation of the'device; Fig. 2 is an end elevation ofthe same; Fig. 3 is a longitudinal sectional view taken through aportion of the same; and. Fig. "lis a transverse sectional view taken onlire t--t of Fig.

In the drawing. the numeral 1 designates i the cylindrical bar of thedevice upon which vthe slides 2 an\d 3 are rotatably and slidl 4to suchan extent that its inner end is moved provided with a set screw 5 havinga knurled 1 g manipulatingihead 6. which is radially adjustable withlrespectto, the bar and whose mner end is'adapted tofproject into thesaid -groove for longitudinalsliding movement therein when.partially-'loosened or for -engagement W1th the bottomwall thereof whentightened to secure the slide in adjusted position upon the bar. Atransversely elongated head 7 is formedupon the outer end of each slideto provide an outer guiding face 8 for cooperation with a radially'disposed marking pin 9 which extends through an opening provided in theadjacent 'end of the bar Lin communication with the groove 4. Thismarking pin fits-tight within the receiving bar opening and is adapted,when first applied, to project outwardly in both directions, one vendthereof being pointed for use in inscribing a line upon a timber or someother desirable object in parallel relation to one edge thereof, alongwhich the guiding surface of the adjacent slide is moved. As the act-iveextremity of the said pin becomes worn, the pin may be adjusted to allowfor this wear by driving'the pin through the bar opening to the desiredextent. The bar l is graduated to provide a longitudinal scale 'oflinear measurement vwhereby the degree of ad'ustment of eachv slide maybe determined. y loosening the set screw upon each slide to a slightextent, the latter may be adjusted longitudinally upon the bar and ma ybe secured in adjusted position by tightening this screw.

It should be apparent that the slides are adapted to engage therespective marking pins, whereby they are limited against longitudinalmovement in the direction of the bar ends and are thusV prevented frombecoming disengaged therefrom under normal conditions. lt is desirable`however. that the slides (should be capable of being removed andreUapplied to the bar without the necessity of rst detaching either ofthe marking pins. y Each slide accordingly is provided withdiametrically opposite. longitudinal slots l0 in communication with itsmedial bore, which may be brought into the saine plane with theprotruding extremities of the corresponding marking pin. when the saidslide has been angularly adjusted upon the bar. after operation of theset screw outward so as not to project into the bar roove 4.

From the foregoing derrription. taken in connection with theaccompanying drawscale inscribed (thereon, .a slide mounted ings, itshould be apparent that I have .pro-r vided @simply constructed andefficient cer'- pent'ens'A gage comprising few parts, and- Which may bereadily assembled or detached.
